Fourteen archaeological sites in the northernmost province of Ha Giang have been excavated in the past fortnight, revealing hundreds of relics believed to appear in the prehistoric and protohistoric times, an expert said.

Assoc. Prof. and Dr. Trinh Nang Chung from the Vietnam Institute of Archaeology said the excavation has taken place since July 26 in mountainous districts, including Dong Van, Meo Vac, and Yen Minh, which are located in the Dong Van Karst Plateau.

In the neighbourhood of Dong Van Town in Dong Van District, the Seo Ho stream site was found to contain prehistoric pebble tools, which were typical for the Palaeolithic Era (Old Stone Age).

Meanwhile, stone axes and grinding bases dating back to the late Neolithic Era (New Stone Age) about 4,000 years ago were unearthed at four sites in Thuong Phung, Xin Cai and Pa Vi communes in Meo Vac District.
